Threats to the site (pressure)
Threat Level 1 Threat Level 2 Timing Scope Severity Result
Agricultural expansion and intensification livestock farming and ranching (includes forest grazing) - agro-industry grazing, ranching or farmin happening now small area/few individuals (<10%) no or imperceptible deterioration low
Climate change and severe weather habitat shifting and alteration happening now majority/most of area/population (50-90%) no or imperceptible deterioration low
Energy production and mining renewable energy likely in short term (within 4 years) small area/few individuals (<10%) no or imperceptible deterioration low
Human intrusions and disturbance recreational activities happening now majority/most of area/population (50-90%) slow but significant deterioration high
Invasive and other problematic species and genes invasive non-native/alien species/diseases - unspecified species happening now some of area/population (10-49%) no or imperceptible deterioration low
